Answer:
a = -5
Step-by-step explanation:
15 - a = 20
Move the constant of 15 to the other side by subtracting it.
-a = 5
Divide by -1 to make a positive.
a = -5
Check.
15 - (-5) = 20
15 + 5 = 20
20 = 20
There are two terms n2 and -5. n2 is the first term and -5 is the second term
<span>2/3x -4=-2
-------------------
Add 4 to each side
</span><span>2/3x-4+4</span>=-<span>2+<span>4
2/3x = 2
-----------------------------
Multiply each side by 3/2
(3/2) * (2/3x) = (3/2) * (2)
x = 3</span></span>
